Future Calls

  ```
  ignisvulpis@namenlos:~/development/hyperledger/indy-sdk/libindy$ find src -name \*\.rs -exec fgrep unsafe {} \; | wc -l

  ```
• New pack / unpack requires disclosure of recipient
  • Cannot hide the receiver of the message like we could with msg_pack
  • Allows having multiple recipients of the same message
  • Should list the drawback in the Aries-RFC? Is there an alternative way that preserves the capability to selectively disclose the recipient?
  • From Kyle Den Hartog
    msg_pack presents problems when dealing with an agent that maintains more than one relationship. For example, if I receive a message, I don't know which key in my agent I should be using to decrypt the message. We can get sender anonymity or receiver anonymity, but I don't believe it's possible to get both and still determine who the message is for.
  • Pack/unpack only exposes the Verkey of the recipients. It does not do forward secrecy.
• Ursa and AMCL:  Discussed in the Ursa call (August 21), but no decision yet.
• Architecture questions for Indy SDK:
  
• PostgreSQL wallet to graduate from "experimental" status?
• Partially completed refactoring of the Request format: INDY-1375 and IS-567
• Maintainership requirements for Indy Node and Indy SDK
• How to handle old pull requests that failed DCO Checks? Close?
• How to handle pull requests for IOS / Swift wrappers? Close and encourage the move to Aries?
• How to handle pull requests for LibVCX? Deprecate?
• Close PR https://github.com/hyperledger/indy-sdk/pull/1048 as something that will be replaced by the advanced schema work?
• HIPE pull requests: https://github.com/hyperledger/indy-hipe/pulls
